Abstract:
Twenty cases of blepharospasm and thirty five cases of hemifacial spasm were treated by injection with Botulinum Toxin A during a fifteen-month period. A total of 74 treatment sessions were given for 7 months follow-up period and the mean dose of 17.81 units per lid and brow was administered according to Scott's method. The mean ages of blepharospasm and hemifacial spasm patients were 59 years and 49 years, respectively. The mean response time of toxin against blepharospasm and hemifacial spasm were 159.9 days and 167.1 days respectively. The maximum effect of toxin appeared in the first 1 month period following injection. The mean preinjection spasm grade was +3.17 in blepharospasm, and +2.41 in hemifacial spasm, and mean postinjection spasm grade was +0.88 in blepharospasm and +0.52 in hemifacial spasm. The mean preinjection muscle strength was +3.15 in blepharospasm, and +3.07 in hemifacial spasm, and mean postinjection muscle strength was +1.12 in blepharospasm, and +1.24 in hemifacial spasm. The complications attributed to toxin injection were lagophthalmos, and epiphora. These ocular complications were localized, mild and transient, and no systemic side effects were noted.
